COLLAIESIBLE BOX AND METHOD 01E MANUFACTURING SMEE.

Application filed. Ziune 7,

T 0 all whom it may concern:

lie it known that T, HENRY LEVINE, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an improvement in Collapsible Boxes and Methods of Manufacturing Same, of which the following is a specification.

My invention relates to collapsible bonesl or cartons adapted to be used as egg contain-- ers or for other like purposes, and also to the method of manufacturing the same.

It has for its general object to provide a box or carton which, though simple in construction, is adapted to protect the eggs against breaking, in an unusually efficient manner.

A further object of my invention is to provide a container constructed of a single sheet of suitable material, the various parts of the container, including the sides, the portions forming the compartments for the eggs, as well as the bottom and the cover being inte- 'ral.

3 Other objects and advantages of my invention will be pointed out in the detailed description thereof which follows, or will be apparent from such description.

In order that my invention may be readily understood and its desirable and practical advantages fully appreclated, reference may be had to the accompanying drawings in which I have illustrated one form of embodiment thereof. However, it will be understood that my invention is susceptible of embodiment in other forms of construction than that shown, and that changes in the details of construction may be made within the scope of the claim without departinc from the said invention.

In the drawings:

Fig. 1 is a plan view of a sheet of material which has been cut and is ready to be folded to form a box or carton embodying my invention;

Fig. 2 is a perspective view showing portions of the sheet in Fig. 1 bent into position to Ipartially form the said box or carton;

ig. 3 shows a perspective view, illustrating the third step in the process of manu facture;

Fig. 4 is a perspective view, showing one end, the top, and'the rear side of the container;

Fig. 5 is a perspective view, showing an 1921. Serial No. 475,647.

end of the container, the top, and the front side of the container; and

Fig. 6 is a transverse sectional view taken along the line G-6 of Figs. 4 and 5.

Referring to the drawings: 1 designates a portion of the sheet from which the box,

carton or container is constructed. The outer edge of the portion 1 is slotted, as indicated at 2, and the said portion 1 is adapted to be folded along the lines 3 and 4 to form the relatively narrow strips 5, 6 and 7 which constitute wall sections of the completed structure. Adjoining the strip 7 is a section or strip 7 which is slit or cut along the angular lines 8 to form the portions 9 which are adapted to be bent upwardly into positions shown in Fig, 2 of the drawings. These portions are each provided with notches or slots 10 in the central edge portions thereof. The adjoining portion of the sheet is adapted to be folded along the lines 11, 12, 13 and 14, to form the relatively narrow strips 16, 17, 18 and 19. A fastening flap 20 having fastening tongues 21 and 22 is connected integrally to the outer edge of the strip or section 19. The strips or sections 7 and 16 are connected to the opposite ends or edges of the upstanding portions 9 of the section 7 by means of triangular connecting strips or tongues 23.

The opposite ends of the strip 17 which constitutes the bottom of the box are extended as shown at 25. These extensions are adapted to be bent or folded along the lines 26 and 27 to form the narrow strips 28 and 29, the latter being narrower than the former. The purpose of these extensions and narrow strips will be pointed out later on herein. The section of strip 16 is provided with inclined angularly shaped slits 32 into which the hook shaped tongues 21 at the opposite ends of the flap 20 are adapted to extend. The said strip or section 16 is also provided with a central slit or opening 35 into which a central tongue 22 upon the flap 20 is adapted to extend,

The sheet having been marked and cut,,a.s indicated in Fig. 1, to form what may be termed a box-blank or pattern, the sections 9 constituting intermediate wall portions 6f the structure and which cooperate with the strip or section 5 to form interior compartments are bent upwardl into the position indicated in Fig. 2 o the drawings. Thereafter, the portion or section 1 is folded along the lines 3, and 4 and also along the flat package for shipping or sending through I line adjacent the ends of the portions .9, as is clearly indicated, and the stri 6 is folded inwardl and over one half portion of the edges the upturned portions 9 and the strip is interlocked with the said portions by means ofthe slots 2 and 10. Thereafter, the portion 16 which constitutes the front wall or side of the completed boxor-container, is folded up against the adjacent edges or ends of the portions 9, and the relatively wide portion 17 is then folded over the top edges of the portions 9, having reference to Fig. 2, which edges, however,- are near the bottom of the completed box or container, and also over the strip or section 6. The relatively wide strip or section 17 constitutes the bottom of the device. The strip" or section 18 is then folded up againstjthe portion 7 and constitutes the rear wall of the box. The extensions 25 at the opposite ends the mails.

In the completed structure, the opposite ends of the top edges of the intermediate wall portions 9 are connected to the opposite side walls of the box by the integral triangular portions 23 as indicated in Fig. 3, which retains the opposite end portions of the said parts 9 in relatively fixed position. The intermediate portions of the parts 9 and also of the intermediate lon itudinally extendingwall section 5 are hel d in relatively stationary position by the interlocking relation of the said portions'and the said wall section.
